But in some occasions it is necessary to have a static IP, for example, to set up a web server or a shoutcast server.
To be able to enjoy the advantages of a static IP, without having to pay the supplement demander by the majority of suppliers of Internet services, there is a solution. It is called DynSite
DynSite is an automatic IP updater, that works in conjunction with a grand quantity of dynamic DNS servers like 2MyDNS, 3Domain.hk, ChangeIP, DNS Made Easy or MyIP to provide a way of keeping the IP associated to a contracted domain, in the cases where the IP varies with time.
Thus, when the router detects an IP change, DynSite will automatically make sure of associating the new IP to the chosen domain, and keep everything in perfectly functional state.
